MTashed is Banned from Twitch... But Why?

Youtuber and Twitch Streamer, MTashed, is banned off of Twitch early this morning. MTashed was wondering what cause the banned and Twitch is saying it because he played with a suspended broadcaster. Was it Dr Disrespect or someone else? The ban is for one week but why did this happen and happening more often to other streamers.
